Impressive pedal, that gives good drive/fuzz. On par with my Proco Rat2 reisue pedal. Beware the 'retro' 3.5mm mono jack power connection! This actually is a modern centre negative polality pedal! you need to use the little adapter cable on the end of a centre neg 2.1mm cable to your power supply. If you have any 2.1mm to 3.5mm jack cables they will be of the 'retro' centre positive type and of no use and could fry your pedal! So i'd stick to using batteries on this pedal to avoid expensive errors!?
